An ectopic rim sign in hepatobiliary scintigraphy.

A 59-year-old man with gangrenous cholecystitis is presented along with an hepatobiliary scan that demonstrated nonvisualization of the gallbladder and a curvilinear area of increased activity in the region of the fissure for the ligamentum teres or common hepatic duct. There was no "rim sign" in the gallbladder fossa. We propose that perforation of the gallbladder and resultant pockets of pus may, through edematous compression of liver parenchyma, produce an ectopic rim sign if inflammation comes in contact with another portion of the liver.

Iron dextran: bone imaging patterns of absorption--a case report.

This case illustrates two different patterns of absorption of Iron Dextran in the gluteal soft tissues due to an intramuscular and a more proper Z-track technique. A 65 year old female presented to the nuclear medicine service for a bone scan to rule out metastatic disease from a surgically resected colon cancer. While the first bone scan showed no evidence of metastases, an abnormal accumulation of Technetium-99m methylene diphosphonate was noted in the left gluteal soft tissue region.
